-# IDKit - World ID SDK (Rust Core)
+# IDKit - World ID SDK for Relying Parties
 
 IDKit is the toolkit for identity online. With IDKit you can easily interact with the [World ID Protocol](https://world.org/world-id).
 
 ## Packages
 
-### Core
-- **`rust/core`**: Core Rust library with shared types, credential handling, session management, and cryptography
-
-### Language Bindings
-- **`js/packages/core`**: ✅ JavaScript/TypeScript with WASM for browser & Node.js ([docs](./js/packages/core/README.md))
-- **`kotlin/`**: Kotlin bindings via UniFFI for Android/JVM
-- **`swift/`**: Swift bindings via UniFFI for iOS/macOS
